The US Army conducted the first flight test of its Northrop Grumman-built Long Endurance Multi-Intelligence Vehicle (LEMV) on 8 August.
The optionally manned hybrid airship was in the air for about 90 minutes during the flight, the army says.
For this initial flight, which took place at Joint Base McGuire-Dix-Lakehurst, New Jersey, a human pilot operated the aircraft. There will be additional manned flights after the vehicle has been inspected, the army says.
The service says that the test sortie met all of its objectives during the flight.
